3 Claims. 1

This is a continuation-in-part of our co-pending application Serial No. 165,714 which was filed on June 2, 1950, now Patent No. 2,611,992.

An object of this invention is to provide an attachment for an exhaust pipe of an engine which takes in free air for mixture with the exhaust gases of the engine and a fluid material which is admixed with the exhaust gases prior to their delivery into the attachment, said attachment including a housing which has a free air inlet at one end wherein the exhaust pipe is located together with an air deflector which directs the free air axially of and toward the exhaust pipe near the discharge end thereof and into a sleeve which is located in the housing, the sleeve being separated from the housing by means of a passage which conducts some of the fluid material laden gas and air back into the sleeve for further admixture, and a discharge member for the housing which opens into the passage at its connection with the outlet end of the sleeve.

A further object of this invention is to provide an air under pressure conductor which is nested with the discharge member for the housing so as to propel the issuing stream of gas and material from the housing outlet member.

Other objects and features of importance will become apparent in following the description of the illustrated forms of the invention.

In the drawings:

Figure 1 is an elevational view of the attachment which constitutes a part of a small vehicle of the manually propelled type;

Figure 2 is a longitudinal sectional view of the housing and certain of its complements;

Figure 3 is an end view of the structure of Figure 2 and taken substantially on the line 33 of Figure 2 and in the direction of the arrows;

Figure 4 is a sectional view taken substantially on the line 44 of Figure 2 and in the direction of the arrows;

Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 2 and in the direction of the arrows; and

Figure 6 is a largely diagrammatic view showing the attachment applied to the exhaust pipe of a multi-cylinder engine of the type used to propel a vehicle larger than that disclosed in Figure 1, the standard pump for applying air under pressure to the conduit being omitted.

The instant device may be used for many purposes, among which are to apply disinfectant, insecticide, fire extinguishing material and many others. The attachment is applicable to a standard engine of the type indicated at [0 or a relatively small engine of the type indicated at l2, both of these engines being provided with exhaust pipes l4 and I6, respectively. Attention is first invited to Figure 2. The exhaust pipe I6 is passed through an opening I8 which is formed at one end of the substantially cylindrical housing 20 and has its discharge end 24 disposed within the housing and supported by the spider 26. This spider is located near the discharge end of the air deflector '28 which is shaped preferably in the form of a frustum of a cone, the wider end portion being within the free air inlet opening it. For additional support the brackets 30 are used to support the exhaust pipe l6 within the opening l8.

There is a sleeve 32 disposed in the housing and concentrically arranged therewith. The sleeve is spaced by means of the supports 34, from the inside surface of the housing 20 and specifically, the side walls thereof, in order to provide an air, gas and fluent material return passage 36 which is of substantially cylindrical form. The supports 34 serve the secondary purpose of providing bafiies for the flowing mate rial in the passage 36.

Inasmuch as the deflector 28 is jointed to the housing at the opening ill, a pocket 38 is formed at the inner end of the passage 36 so as to direct the stream passing through the passage into the substantially circular opening 40 which is defined by the space between the inner end of the sleeve .32 into which the deflector 28 is fitted and the outer surface of the deflector.

A discharge member 42 for the housing 20 is preferably substantially circular in cross section and opens into the housing at the place where the passage 36 merges or connects with the discharge end of the sleeve 32. In view of the location of the discharge member 42 the mixture of air, gas and fluent material is taken from the housing for discharge only in part, some of the material, air and gas, being returned through the passage 36 for recirculation.

A conduit 46 is operatively connected with the discharge member 42. The conduit is made up of a flexible tube 48 and a rigid tube 50 which is connected to it. The rigid tube constitutes a nozzle and the lower wall 54 at the discharge end thereof is curved similar to the curvature of a part of the discharge member 42 so that the discharge member and the nozzle portion of the conduit 46 may be nested with each other. The conduit is operatively connected with a.

put. A storage tank 60 is provided with a valve:

62 in order to control the outlet, oi the tank and a conduit 64, preferably of the flexible type,

extends from the valve 62 and connects with. a

rate of flow control valve 66 which is carried by the pipe 68. The pipe 68 opens into the exhaustpipe upstream of the discharge end of. the. ex:- haust pipe so that the fluent material is first mixed; with the hot. exhaust.- gases prior to dilution with the free air entering the air inlet I8.

In. operation, the engine. H] or I2 is rendered operative in the usual way. This causes exhaust gases to: pass through the exhaust pipes of. the. engines and into the sleeve 32 By manipulating theevalves- 62. and; 65 properly, a quantity of fluent material is; introduced into the exhaust pipe. and admixed with the exhaust gases for dispersal in the: sleeve 32. The material, that is, exhaust. gases and. fluent. material. passes through. the sleeve, causing a low pressure region in the. deflee-tor 2d;- whiehdraws-free: air throughthe opening This free air, fluent. material, and exha'ust gas is discharged from the sleeve so as to strike the end wall. ii). of. thehousing 2! causing itito. he deflected outwardly andrearwardly. The part of the mixture which, is deflected rearwardly passes. through the passage 36 and. back. into the sleeve 32. through the, opening 40. The. remainder oi? the. mixture passes. through the discharge member 42. and this. remainder of material is propelled by the actionof the air stream oi the, nozzle 59..

In. instances wherein the, attachment. is. to be used with a relatively large piece. of equipment, for example a tractor, it. is suitably mounted.

' When the attachment is to bev used. with a relatively small vehicle. suitable. provision is made, as the hand truck 12'. disclosed. in Figure 1 for supporting the component parts.

Having; described. the. invention, what is claimed a inew is:

1. In. an. attachment for a, pipe. delivering gas. under pressure, a housing. having. side walls, one end. wall, and. a. free air inlet opening in the op posite end of the housing, an. inwardly directed and, tapered. air deflector locatedinsaid housing and said air. inlet. opening, means for supporting the gas discharge. end of; the pipe within and adjacent to the discharge end of said deflector, a sleeve disposed in said housing and extending axially thereof, said sleeve being spaced from the inner surface of said housing to provide an air passage between said sleeve and said housing, said sleeve being arranged to conduct air from said deflector and gas from the pipe against said end wall whence some of the air and gas is directed through said passage, the end of said sleeve adjacent to. said. deflector being spaced from the deflector to provide an inlet to deliver gas and air from said passage into said sleeve, and an outlet member connected with said housing adiacent. to said end wall and opening into said housing at the place where said passage communicates with the discharge end of said sleeve.
